To all whom it may concern:

Be it known that I, GEORGE F. drNNrs, a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and useful Improvements in Anchors and Clips for lVindow-l/Yashers Harness, of which the following is a specification, I c 1 This invention relates to improvements in anchors and clips for window washers harness.

One of the objects of the invention is to provide an improved anchor and cooperating clip for attachment thereto; 7

Another object is to provide a clip and anchor in which the clip must be turned substantially ninety degrees to its operating position in order to attach it to or to remove it from the supporting anchor.

Another object is to provide a strong, durable, one-piece'clip, safe and reliable, which cannot be removed from its supporting anchor until the operator using it has relieved the rope attached thereto of his weight.

Another object is to provide a clip that may be readily and conveniently attachedto and removed from its supporting anchor,

' projecting from the face ofthe wall of the building.

Another object is to provide a one-piece clip; another object is. to'iprovide a peculiar form of one head anchor.

Other, further and more specific objects of the invention will become readily apparent to persons skilled in the art from a consideration of the following description when taken in conjunction with the drawings, wherein Fig. 1 shows a plan view of the anchor as it is arranged in a brick wall of 2a building and shows the clip attached thereto, in section.

Fig. 2 is an end elevation of the anchor.

Fig. 3 is a central longitudinal section of the clip, and V Fig. 4 is an inverted plan view of the same.

Fig. 5 is a fragmentary elevation showing tally elongated, having'a'neckfi connecting Specification of Letters Patent. Patented Jaj 31 1922 i Application filed December 31, 1919. seminal 348,615.

the body part of the anchor to theiheadr flange 7 for intimate contact with the outer face of the wall, is extended horizontally to 7 grees' fromjthe inner'face ofthe flange"7',to-

bridge the joint betweenltwo horizontally adjacent bricks ,9 and. 1Q shown in broken. lines-in Fig. 1.; Theshank '8 is groovedfas at 11, and is provided with connecting ribs 12 or depressions, to provide abutments to interlock with the mortar and render the shank of the anchor more difficult to remove from A thewall; A downward or upturned end 13, for contact with the inner surface of a course 0t brick, serves also to retain the anchor in place. The thickness of the anchor is no greaterthan the thickness of the mortar-14 between the respective courses of bricks. Any sort of anchor shank for the. purpose of holding the head 5 in propersupport building will, however, answer the purpose.

The clip 15 consists of a single piece having a rectangular part 16, with an oblong opening 17 therein, through which the head 5 of the anchor is passed. Surrounding the opening 17 is a rib 18 to receive the edges19 of the head after the clip has been'moved substantially ninety degrees from the position necessary for placing it upon the head. The two side members 20, of the clip, are connected together as at 21 and 22 therebyj making it a very strong structure. Extending axially from one end of the body of the 1 clip is a ring 23, within which to thread'a washers harness. A flange 24 is located between the body part of the clip and the underside of the ringto-provide an opening 25 for a hook to :support'the water pail of the window washer. Av rib or rabbet 26' may clip to give greater strength and between with the outer surface of the wall of the rope to be connected to the belt of acwindow i bound one end of the rectangular part of the which the rib or flange 18 the head 5 of the anchor is received.

The rib 18 of the clip near the upper end thereof strengthens the'structure, and when the clip is in place, it is in contact with the neck 6 and'receives substantially all of the weight suspended on the rope, that is securedinthering23.@ v c To place the clip upon'the anchor, the .op-

erator holds the clip with-its longitudinal axis in a substantially horizontal plane and moves it toward the anchor so that the head 5 of the anchor will enter the opening 1-7 inthe clip; he then turns the clip so that its longitudinal axis is in a vertical plane. The flange 19 of the head overlies the ribs 18 of V the clip and prevents the latter from leav- 7 therein; a loop extending laterally and longitu'dinally beyond, the opening, within which to secure a rope; a flange between the "loop and base having an opening through which to support a pail and a rib extending around three sides of the oblong opening, located laterally between the base and loop. 2. An anchor having a head, an enlarged contact with a wall of a structure, an intermediate neck smaller than the head and flange and interconnecting the same, and a shank extending at an angle to the flange to lie between adjacent courses of the brick forming the wall and to bridge at least one joint between bricks in the same course;

3. An anchor comprising a flange having a flat rear face for contacting the wall of a building, a shank extending at an angle rearwardly from the flange to lie betweenad- .jacent horizontal courses of brick forming the wall and bridge the joint between two adjacent bricks in the same course, and a head secured to the forward face of the flange by a restricted neck.

In testimony whereof I hereunto subscribe my name.
